Subject: [PATCH v13 06/20] dt-bindings: mtd: Document nand-ecc-engine
Date: Thu, 27 Aug 2020 10:51:54 +0200 [thread overview]
Message-ID: <20200827085208.16276-7-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20200827085208.16276-1-miquel.raynal@bootlin.com>
This property is needed to precisely point to the hardware ECC engine
to use when there are several of them available. Here, hardware also
refers to the on-die possibility.
